FRANK WARCUP, OF WESTERNVILLE, NEW YORK.

DOOR-LOCK.

To all whom it may concern:

-Be it known that I, FRANK WAncur, a citizen of the United States, residing at lVesternville, in the county of Oneida and State of New York, have invented a new and useful Improvement in Door-Locks, of which the following is a specification.

My invention relates to improvements in door locks in which the door is made to open and close simply by a slight push or pull on the handle, and can be attached to or removed from the door more simply and more easily than the common look.

I attain these objects by the mechanism illustrated in the accompanying drawing in which Figure 1: is a top view of the entire lock: Fig. 2: is a front edge view of the same: Fig. 3 is a side view of the same: Fig. 4: is a view of the sliding case which is a part of the lock equipment. 7

The lock works on and through a metal plate which is fitted over the edge of the door, with openings for the key and handle and lock.

Referring now to these figures, I provide a U-shaped bolt operating lever A, the-ends of the extensions of which are provided with lateral elongations upon which are secured handles as seen particularly in Fig. 1, the lever A being extended horizontally through the side slots of a rectangular lock casing F which is adapted to be secured to the free edge of the door after it has been suitably cut away to receive the same. Centrally of its cross-bar, the U-shaped lever A is provided with a bolt engaging boss, as seen also in Fig. 1, and at one side of this'boss and preferably adjacent the inner side of the bolt casing F, the cross-bar of the lever is provided with vertical trunnions journaled through openings in the upper and lower walls of a sliding, case C, whereby to form a pivot upon which the lever may be horizontally oscillated within the confines of the sliding slots of the casing F. The upper and lower slots of the sliding case C are provided with vertical lips slidably disposed within guide strips N secured to the inner surface of the inner wall of the lock casing F above and below its side openings before mentioned, and is provided in its lower wall with an intermediate longitudinal slotted opening M and with longitudinally spaced apertures L and 0 adjacent its inner end. Secured through the inner wall of the lock Specification of Letters Patent.

. ed for engagement within either of the apertures L and 0 before mentioned.

Below the sliding case C, the inner wall of the casing F is provided with a key frame K and a key slot P through the latter of which a key may be inserted, and upon turning movement, projected upwardly through the intermediate slottedv opening M of the casing in order to engage and lift the spring members D to free the stud of the lower spring member from the aperture 0, it being noted that upon inward movement of the sliding case C to engage the spring locking stud with aperture 0, the lever A which is pivoted to this slid-ing case will be carried inward to the inner limits of the slots of the casing F and with the parts locked in this position as shown in Figs. land 3, the lever A will be prevented from movement sufiicient to release the locking bolt to be now mentioned. The outer end wall of the casing F is provided with a bolt receiving aperture, and a sliding bolt G which is mounted with in a bolt case H set into the door frame and is adapted to cooperate with the lock casing to form a latch, this bolt being spring pressed as shown both in Figs. 1 and 3.

As shown on the drawing, the door is closed and locked. To open, the key is inserted in the key hole, either from inside or outside, and turned until it passes through opening M. in the bottom of sliding case C. and, bearing against under side of spring D. (which spring is secured by bolt E. to outer casing of lock F and is therefore immovable horizontally) raises the projecting catch on under side of spring D. out of the opening 0. In the above position of the spring and its catch, the sliding case C. can be pushed horizontally toward the latch G. until the catch under spring D. en ages with the opening L. and prevents furt her movement of the sliding case C. The sliding case C. is moved toward the latch G. as stated above, by means of the U. shaped lever or handle'A, as this handle, being secured by the pin B. which passes through the top and bottom of the sliding case C., transmits its movements to the sliding case until the catch engages with opening L. The sliding case (1, now being immovable, the U. shaped lever or handle A. will, under further pressure, swing on the pin 13. as a pivot and by this movement, will push the latch G. sutliciently far enough back against the spring in its recess H. in the door jamb,

and suhiciently far out of the door, to permit the door to be opened. is merely to afiford entrance and support for the key. Parts N. are guides for sliding casing C.

I make no separate claim for the method of unlocking alone, but the foregoing description is given to illustrate the operation of my invention.

I claim:

1. The combination with a sliding bolt, of a lock casing having a bolt receiving aperture, and a til-shaped releasing member havinghandle extensions at its outer ends, the said member being extended through the casing in a horizontal plane and in line with the sliding bolt and being pivoted at one side of a center within the casing adjacent the said bolt, all for the purpose described.

2. The combination with a sliding belt, of a lock casing having a bolt receiving apex ture at one end and side slots, a bolt releasing member extended horizontally through the side slots of the casing and having handles at its outer ends, said member being The casing K.

pivoted Within the casing adjacent and in line with the bolt receiving aperture, asl'iding member supported within the casing and carrying the pivot of the member whereby to adjust the latter within the confines of the casing side slots, and means whereby to lock the sliding member, all for the purpose described.

3. The combination with a sliding bolt, of

a lock casing having a bolt receiving aperture at one end and side slots, a bolt releasing member extended horizontally through the side slots of the casing and having handles at its outer ends, said member being pivoted within the casing adjacent and in line with the bolt receiving aperture, a sliding member supported within the casing and carrying the pivot of the member where by to adjust the latter within the confines i i Gopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D'.
